I am surprised at the other comments here that state sketching is a skill worth preserving. That's something the author of the article clearly states, hist call to discussion is about technical drawing by hand. And I'm surprised this is still a topic. I studied architecture more than 25 years ago and at that time hand drawing was already phasing out. I have never practiced architecture since then and never thought there would be a debate about drawing by hand again. From what I heard of friends being in the business, doing 2D-drawings isn't a thing in bigger projects anymore, as it is way more economical and less error prone to do the plans with 3D modeling.
